VAPOR-LAMP.

SPECIFICATION forming partl of Letters Patent No. 757,780, dated April 19, 1904. Application iled July 5, 1901. Serial Fo. 67,227. (No model.)

To all whom, it may concern:

Be it known that I, EDWARD Snrrz, a citizen of the United States, residing at Peoria, in the county of Peoria and State of Illinois, have invented certain new and useful Improvements in Vapor-Lamps; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

This invention pertains to vapor-lamps of that class which use vapor produced from gasolene.

The object of my invention is to improve on lamps of this class in providing a new form of generator.

Another object is to provide means for regulating the fiow of vapor, and thus be enabled to turn the light up or down.

Still another object is to heat the generator by means of the illuminated incandescent mantles usually employed, so that the vapor is produced easily and freely and in amount sufiicient toprovide for feeding several burners at a time.

In the accompanying drawings, Figure 1 represents an elevation of the lamp with some ci' its pipes in cross-section. Fig. 2 is a longitudinal section of the generator and the conducting-pipes. Fig. 3 is a perspective View of a iilter-plug shown in Fig. 2. Fig. 4 is an air-inlet tube, showing a covering-shell in section for inclosing the same. Fig. 5 is a sectional view of a valve, showing the means for operating it. Fig. 6 is a cross-section of the air-inlet tube shown in Fig. 4. Fig. 7 Vis va view showing the means for operating the regulating-valves of thelamp. Fig. 8 is a View of the under side of the same.

In Fig. l, A is a tube which is hung from the ceiling in any good manner and from which the lamp is suspended. rJhe lower end of said tube terminates in the casing of a valve H. A tube A also extends from the said Valve-casing to a generator C below, the upper end of said tube being closed by the valvecasing and the lower end terminating at a union B on said generator. The lower end of the generator supports a table D by screwing thereinto, and into the projecting boss of said table is screwed a casting E, having passages formed in it which receive vapor from a vapor-tube I, to be described. Said casting E consists oi' a vertical portion having radiating arms F at its lower extremity,having continuations of the vapor-passages which end in jet-orifices K, such orifices being controlled by valves L. A tube G conveys gasolene from a receptacle placed in the basement of the building to be lighted or in the attic,which, however, is not shown and from which the gasolene .is made to flow through thevalve H,by which the flow is controlled, thence into a continuation of such pipe Gr, whose lower extremity terminates within the generator C at about its middle or near the bottom. A Vapor-tube I, secured in the bottom of the generator and extending down into the casting E, arises above the generator, as shown in Figs. 2 and 3, its end being open, as shown. a continuation of said pipe G to the jet-orifices. The end of the tube G within the receptacle is covered by a tube of wire-gauze, and the entire space in the receptacle is filled with asbestos-fiber, or other straining material, so that foreign particles in the gasolene in ilow- 'Ying from the open end of said pipe Gr will be caught in the material and not allowed to reach the exit in the vapor-pipe I, and'in this Way all heavy foreign matter carried by the gasolene will be left in the said straining material. The vapor pipe Iis carried down into the casting and there discontinued, or it may be carried to the jet-orifices, if desired, though this is not necessary. The jets in the device illustrated are three in number; but of course any number may be employed. One of` them is shown in Fig. 5 at F, it being secured `to the casting E in the usual manner. Each of the valve-stems L is provided with a gear M, and a central gear N is carried at the end oi' the casting E in any good manner and meshes with said pinion of the valve-stems. Said gear has a .key or finger grasp O, by which it may be turned, and thus impart motion to the pinions M, as shown in Fig. 8. Beneath the jetoriices and hung from the casting E is a cup I), into which alcohol is poured and burned to heat the jet-orifices and the generator C. The

ame of the burning Huid arises through open This in reality forms IOO ings (not shown) ina globe support Q and openingR in the table which supports the" mantles and heats the said generator, thus rarefying the gasolene therein and vaporizing the same. Above the jet-orifices F is a mixingtube, which consists of a tube whose upper end'is covered with gauze and whose lower end is. provided with openings T and lugs U.

The lower end is surrounded by a sleeve V,

which is held away from the tube S by the lugs U. The said tube S being heated by the vapor which burns within the mantles W conducts heat down to the valve, with which it is in close Contact, thereby keeping the vapor hot and producingbetter and whiter light. The sleeve V prevents air-drafts from affecting the steady burning' of the lamp, it being well known that any draft, however slight, will cause a flickering of the lights. The open space at the top and bottom of the sleeve admits sufiicient air to the vapor to make the combustion perfect. The mantles X are supported by the usual wires Y, held in bracket Z above, as shown. The generator C has three wings, only two of which appear, however, and indicated by C2. These project toward the mantles and absorb much heat therefrom and at the same time steady them to guard against jarring and breakage of the delicate filament. The heat absorbed raises the temperature of the fluid within, which boils and passes down through the tube I to the jet-orifices. I have found that by letting the gasolene intothe generator far below the outlet-pipe better results are obtained, for the reason that the fiuid is heated and vaporized before passing downto the orifices. If the gasolene were permitted to fiow directly out from the bottom of the generator before being' rareficd, it would spout out of the valves at the bottom in liquid form, because the heat below would not be sucient to produce vaporization to the desired extent. By boiling the fiuid it is purified and made to vaporize readily and rise to the exit, whence it passes to the said orifices. The fiuid is vaporized as fast as it enters vand fills the pipe A and is kept under much pressure by reason of the heat from the burners which surround the generator in which said pressure is -generated. The gasolene enters the said generator from the conducting-tube G and vaporizes as it is deposited in the asbestos filling and then passes to the jet-orifices through the vapor-tube I. The gasolene after escaping from the lower end of the pipe Gr within the generator C rises to the end of the pipe I and descends to the jet-orifice. Above the generator the pipe A is covered by asbestos, and a tube is placed over the asbestos, this being provided in order to prevent heat from.

the generator and mantles rarefying the gasolcne in the pipe A and preventing the flow thereof downward into the said generator. It is found that this pipe if kept comparatively cool will not prevent the downward fiow of fluid; but if hot such downward movement will be retarded. A `globe b rests upon the bracket Q and takes the place of the usual chimneys for the mantles. A suitable hood or reflector c is employed to cast the light beneath the lamp, thus completing said lamp as I prefer to construct it.

The method of supporting the reflector I have not shown; but any desired means may be employed. The globe-support or bracket Q rests upon lugs f on the portion F; but any other means may of course be resorted to. My lamp thus constructed has been found to give excellent results, and a point I desire to bring out fully is the ability to have a large or small light by turning the valves by means of the gear N. I provide a stop d at three places in the periphery of the said gear, so that it is only necessaryto turn the key O to open the valves L. This allows the full charge of vapor to pass to the jet-orices, and the full power of the light is then given out.

Having thus described my invention, I claiml. In a vapor-lamp, a vertical generator adapted to be heatedby the mantles of such lamp, a vapor-tube passing vertically through IOO the entire length of the said generator and open at its upper end within the top of such generator, such tube descending to the jet-orifices of the lamp for conducting vapor thereto, a fluidconducting tube descending into the generator parallel with the said vapor-tube with its open endv near the bottom of the said generator so that the two open ends of both tubes overlap each other whereby the 'fluid is carried down past the end of one t0 the bottom of the generator, is vaporized and arises to the top of the generator and then descends through the other tube for the purposes described and a filling of straining material in such generator through which the vapor and fluid pass substantially as described. y n

2. A vapor-lamp comprising an inlet-tube IIO G, the valve H for controlling the flow of Y fluid, the generator C into which the open end of said tube descends, a filling of straining material within the generator, the tube Iv gaging said pinions for operating the Valves simultaneously whereby they may be opened and closed as described.

3. In a vapor-lamp the usual burners therefor, the gasolene-supply pipe thereto, valves for controlling the iow of vapor to the burners and means for operating such valves in a simultaneous manner whereby the light or' each burner may be turned up or down to the same degree.

4. In a vapor-lamp, burners therefor, a needle-valve for each burner, a pinion M for each valve, a central gear N for operating the pinions simultaneously for the purposes set forth and a series of lugs on the periphery of the gear for limiting the movement thereof and the consequent movement of the pinions.

5. In a gasolene-vapor lamp, a tube A for supporting the lamp, the vertical generator C attached thereto, an insulating-covering` for the tube A, a gasolene-conducting tube Gr within the tube A, a valve for governing the fiow of the Huid therethrough, said tube G arranged substantially as and for the purposesl set forth.

In testimony whereof` I aiix my signature in presence of two witnesses.
